The TPS63805YFFR by Texas Instruments is a high-efficiency, low-quiescent current buck-boost converter with a tiny solution size. It has two separate channels and a maximum output current of two amps with a quiescent current of only 11 uA. The small, 15-DSBGA package makes it ideal for use in applications with space constraints. It has an operating temperature range of -40°C to +125°C, making it suitable for a wide range of applications. It is a switching voltage regulator that can operate in buck, buck-boost, or boost mode depending on the input voltage. This allows the output voltage to be accurately regulated over a wide input voltage range. This versatile converter also features a low external component count, requiring only a few external capacitors for operation.
